Because the whole daily reward system's point is to incentivise people to log in daily, whether you think this is a good idea or not, that's what CDPR think and unless you have strong proofs that other ones work better i do not think that they will change it. And at the same time they do not want to force you to grind too much to have some kind of reward, but still allow you to get decent rewards. Do not forget that tons of games only give you a reward for logging in each day, and some other games only have daily quests that allow you to advance, and those games aren't necessarily any worse or better than the others. I still think that 3 games won or 6 games lost is fairly easy to get daily. Worst case scenario they would not reset your dailies if you don't go past the first tier, but having two tiers cumulate 3 times over 3 days is completely unfair for other people that take some of their time to log in daily to get those cards. The correct reaction to "oh noes i'm not getting enough rewards because i don't play enough" is simply "well try to take some more of your time to play enough and get the rewards you consider as enough" from me, we all have our own lives and we all have decisions to make, if you decide to do something else than play gwent well that's your life and you are master of it, but assume the consequences of your choice, and don't go full caps when people have different opinions on the matter. You are not the only one that can feel that something is unfair, and doing the changes you talked about will actually make a lot of people think that their daily log ins have lost A LOT of their rewarding power because of the change you are asking for
And you didn't counter any of my arguments about heartstone vs gwent there are three different designs for 2 cards only, and i'm pretty sure that the odds of getting one of those three designs were 1/3 of other cards and the fact that we're getting tons of reaver hunters is a bug. Meanwhile in Heartstone you have lots of different pack types that 99% of the time only synergize with cards of that same card type but since you're not going to get enough gold by the time the event ends you will probably not be able to make even half a decent day with cards of that event. Gwent doesn't have that, also you get 4 gold and 6 silver cards on the base decks and still get silver and gold cards at a decent rate where as in heartstone you don't get any legendary card unless you pay shittons of packs.
